June 15 is the official start of Arizona’s Summer Monsoon. This is the time of year when weather patterns change and the potential for extreme weather – such as dust storms, thunderstorms, wind, lightning and downpours – increases. This indoor presentation will explain some of the conditions that bring about this weather, why this season is important to desert plants and animals and how you can stay safe when Mother Nature livens things up. Meet inside the Visitor Center. 10-11am.
